I need help, having problems with plants in veg. leathery, frumpled?, curling down, only on new growth. here's specs - indoor hydro, 6" grodan cubes, house n garden nutes, 62-72 degree room, water temp 57F, hum 60-75%, 1k lite at least 4' away(in veg). I first saw this problem in late october and am leaning toward cold air or water. I've been using H&G for years and never seen this, but we're in a new room. It has A/C and dehumidifier. Anyone seen this before?
